Bomhoff served as Deputy Prime Minister and Minister of Health, Welfare and Sport from 22 July 2002 to his resignation on 16 October of that year. Bomhoff served as a member of the Pim Fortuyn List (LPF) despite having been a member of the Labor Party (PvdA) until that election.
Resignation
During his time in the cabinet, Bomhoff came under attack from the Minister of Economic Affairs, Herman Heinsbroek, a fellow member of the LPF. Heinsbroek stated publicly that Bomhoff was a failure as Deputy Prime Minister and started testing the waters for a new political party. A coalition partner, the VVD party, convinced the other LPF ministers that they could replace both Bomhoff and Heinsbroek. Bomhoff told his colleagues that this would not work, but they forced him and Heinsbroek to resign. As predicted by Bomhoff and several major newspapers, the coalition partners then did not allow the LPF to put forward two new ministers, but decided to immediately dissolve parliament and call for new elections. LPF never returned to the Dutch cabinet.
Bomhoff returned to academia after leaving the government, accepting positions as professor first at the University of Bahrain and later at the University of Nottingham. He is currently serving as a professor of Economics in Monash University's Sunway Campus in Malaysia, in the School of Business. Bomhoff has written a book about his time in government, titled Blinde Ambitie (Blind Ambition). He has been the Malaysian principal researcher for the World Values Survey and has published his recent research in the Journal of Cross-Cultural Psychology and in Public Choice.
Bomhoff belongs to the Old Catholic Church but considers his religion a private matter. His religious views are quite orthodox. He is married since 1976 and has two children.
